My kids (kindergarten and 2nd grade) know the rules... they are allowed a snack and juice, then it's homework time. After I check it, it goes back into the folder, folder in the backpack and backpack put away. It's about 20 minutes from walking in the door to handing me the homework, at the most. Nightly reading is started 20 minutes before bedtime. Sometimes we go a bit over, but my kids go to bed early, so it's no problem. My kindergarten and I "play school" when she gets home, but she does homework alongside my son when he gets home in the afternoon.
Last fall, one of the mom's from my son's class started a big thing over the kid's "45 minutes" of homework every night. As I'm the parent entrusted to check this stuff in on my volunteer day, I am aware her son did not do 45 minutes daily. He turned in his homework maybe 3x a month. The other moms (2) who stood with her had the same problem. They were ignored basically. How can you complain about a rule you don't follow? At these ages, homework is really simple - a way to get them in the habit, with only the occasional fun weekend project and no homework on Fridays.
There are times when we have something going on after school and homework has to wait. As my kids are early birds that wake up before 6am (no matter what time they went to bed), we do it after breakfast on those mornings... and at this point, it's THEM reminding ME. So much better than when I grew up - latchkey kid, no supervision afterschool, dinner at 8 or 9pm, then dishes and bed. The only time homework was mentioned or asked about was when report cards came out and my mother would tell the teachers she had a special place and time for us to do our homework every night, even though she worked. Boy... I remember asking her where that place was when I was 9 right in front of the teacher... after the beating ended, I never asked again.
